PETER FAUST, OF NEW YORK, N. Y.

MUSTARD-MILL.

SPECIFICATION forming part of Letters Patent No. 631,931, dated August 29, 1899. Application filed November 19, 1898. $erial No. 696,930. (No model.)

To all whom, it may concern:

Be it known that I, PETER FAUST, a citizen of the United States, residing at New York, (Brooklyn,) in the countyof Kings and State of New York, have invented certain new-and useful Improvements in lVIustard-ll/Iills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to grinding-mil1s,and more particularly to the mills used for grinding mustard-seed.

This invention consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a vertical sec- Fig. 2 is a plan view,

tion through the mill. some parts being shown broken away to show a portion of the revoluble stone and the scraper.

A is the frame of the mill, which is of any approved construction.

B is a non-revoluble grinding-stone having an eye I) and a conical concave or dished under surface Z2. The stone B is supported from the frame in any approved manner which will permit its exact position to be adjusted.

C is an iron shell which carries the stone B, and c are arms which project from the shell.

D are screw-threaded studs or pillars secured to the frame and supporting the arms 0, and d are nuts on the said studs, by means of which the exact position of the stone Bis adjusted. The studs or pillars D are preferably secured toa top plate A, which formsa portion of the frame A, and which is connected to the stationary portion of the frame by hinges a. The top plate and the top stone can be turned over on the hinges a, so as to give access to the faces of the stones, and the top stone can be returned to its exact original position without altering its adjustment and connection with the studs D. Bolts 0, or other approved fastening devices are provided to rigidly secure the hinged top plateto the stationary part of the frame when the mill is at work.

E is the revoluble stone which is carried by an iron shell 6. The upper surface e of the stone E is conical or convex to conform to the under surface of the stone B.

F is a ring, of hardwood or other similar non-corrosible material, secured around the stone E. It is important that no corrosible material, such as iron, be used in a mustardmill in any position where the ground mustard can come in contact with it, as the chemical substances in the mustard eat away iron rapidly.

The stone E is mounted on a shaft f, which is journaled in a bearing f, which is preferably babbitted and adjustable. ing f is supported from the frame in anyapproved manner. The lower end of the shaft f runs in a step G, having a steel wear plate or bush 9, and this step is carried by a lever H, pivoted to the frame at one end by a pin h. I is a screw-threaded rod pivoted to the other end of the lever H, and i is a handwheel supported by the frame and engaging with the screw-threaded end portion of thesaid rod. The hand-wheel i afiords a means for raising and lowering the stone E. The two stones are ground together with smooth faces and are then dressed in any approved manner.

. J is a bevel-toothed wheel which is splined to the shaft f, and j is a bracket secured to the frame and supporting the said wheel.

K is a horizontal shaft for driving the mill journaled in bearings 7;. A bevel-toothed pinion 7c is secured on one end of the shaft K and gears into the wheel J. Fast and loose pulleys m m are mounted on the shaft K in the usual manner for driving the mill.

0 is a scraper, of hard wood, which bears against the periphery of the stone E and the hard-wood ring F. The scraper O is carried by an iron support or bracket 19, which is secured to the frame in anyconvenient position.

P is a vessel for receiving the ground mustard which drops from the scraper. The material to be ground is fed through the eye of the top stone.

In order to keep the stones cool while the mill is at work, the shell 0 is provided with a water-chamber q, and the shell 6 is provided with a watcr-chamber q. \Vater is caused to circulate through these chambers. The mill can be worked without these means for keeping the stones cool, but it is found advantageous to use them. When the shells are provided with water-chambers, they are prefer- This bearchamber g. This pipe R has a branch 0', which is arranged centrally of the eye of the stone. S is a catch-pipe or funnel secured to the shell 8 of the lower stone and arranged centrally thereof so as to receive the water from the branch 1-. The catch-pipe S has a discharge-opening s at its lower part, which guides the water into the chamber q, and the motion of the stone throws the water toward the periphery of the chamber.

The shaft f has a central bore .9, through which the water escapes from the chamber q after the said chamber, has been fi led with water above thelevel of the top of the shaft I, which projects upward in the chamber, so as to retain the water in it. A spout T is secured to the side of the shaft andis connected with the central bore 5-.

T is a circular trough supported from the frame A under the spout T and receiving the water from it as the shaft revolves. The

trough is supported by hangers t, and it is provided with a spout t for discharging the water clear of the mill.

What I claim is 1. In a mustard-mill, the combination, with a grinding-stone, of a shell of corrosible metal encircling the said stone, and a ring of noncorrosible material secured around the said stone and protecting the upper edge of the said shell, substantially as set forth.

2. In a mustard-mill, the combination, with a grinding-stone, of ashell of corrosible metal encircling the said stone, and a ring of noncorrosible material secured around'the stone above the said shell and overlapping the periphery of the said shell, substantially as described and shown. 7

3. In a grinding-mill, the combination, with a grindingrstone, of ashellcar'ryi'n g the grindg stone and fo med of two supe po e plates, one of the said plates fitting within a" peripheral flange on the other plate and the said plates having a space or chamber between them for water, and means for securing the said plates together, substantially as set forth.

In testimony whereof I affix my signature
